Failure Rate Estimation in a Dynamic Environment [PDF]
Economic Quality Control, 2015 Abstract We present a method to assess the reliability of a material operating in a dynamic environment. The dynamic environment is represented as a sequence of shocks governed by a self-exciting point process. The time-to-failure of the material is assumed to have a piecewise exponential distribution.

An Efficient Implementation of Fixed Failure-Rate Ratio Test for GNSS Ambiguity Resolution
Sensors, 2016 Ambiguity Resolution (AR) plays a vital role in precise GNSS positioning. Correctly-fixed integer ambiguities can significantly improve the positioning solution, while incorrectly-fixed integer ambiguities can bring large positioning errors and ...

An Innovative Model of Reliability—The Pseudo-Entropic Model
Entropy, 2019 There is an entire field of literature on reliability models. Building reliability models is most frequently done by starting from the failure rate (or hazard rate). Creating a reliability model starts with the specific type of product behavior over time,

Standardization of cumulative failure rates [PDF]
Demography, 1975 Abstract A method is proposed for standardizing life table cumulative failure rates for various cohorts so that they are adjusted to the distribution of exposure by age group for a particular cohort. An approximate standard error for the standardized cumulative failure rate is presented. Application of the methodology is illustrated by a

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Sickle cell disease (SCD) is a chronic, inherited hemoglobinopathy that requires frequent hospitalization for disease‐related complications. Canadian data on inpatient care is limited. This study compared caregiver‐reported hospital experiences of children with SCD to those with cystic fibrosis (CF), a chronic, autosomal recessive ...
